What is that really bright star in the sky just after sunset?
You could also be referring to the planet Mercury. It can be seen just before Sunrise and just after Sunset. As mercury is nearest planet to the Sun, it is always seen very close to the Sun in the Sky. We can’t see it in the morning because the is too bright and at night it is below the horizon. Hence, it is visible only for a few moments just before Sunrise and just after Sunset very near the horizon.
